如何使用 Java 将文本添加到图像。

解决方案

以下是使用 Java 将文本添加到图像中的程序。

import org.opencv.core.Core;
import org.opencv.core.Mat;
import org.opencv.core.Point;
import org.opencv.core.Scalar;

import org.opencv.imgcodecs.Imgcodecs;
import org.opencv.imgproc.Imgproc;

public class AddingTextToImage {
   public static void main(String args[]) {

      //Loading the OpenCV core library
      System.loadLibrary( Core.NATIVE_LIBRARY_NAME );

      //Reading the Image from the file and storing it in to a Matrix object
      String file = "C:/opencv/logo.jpg";
      Mat matrix = Imgcodecs.imread(file);

      //Adding Text
      Imgproc.putText(matrix,        //Matrix obj of the image
         "Tutorialspoint",           //Text to be added
         new Point(100, 390),        //point
         Core.FONT_HERSHEY_SIMPLEX , //front face
         1,                          //front scale
         new Scalar(0, 0, 0),        //Scalar object for color
         5);                         //Thickness

      Imgcodecs.imwrite("C:/opencv/addingTextOP.jpg", matrix);
      System.out.println("Image Processed");
   }
}
